Bicyclic compound and use thereof for medical purposes

ABSTRACT

Since a compound represented by the general formula (I) (wherein definition of each group is as described in the specification), a salt thereof, a solvate thereof, or a prodrug thereof has strong and sustaining intraocular pressure lowering activity and, further, has no side effect on eyes such as ocular stimulating property (hyperemia, corneal clouding etc.), aqueous humor protein rise etc., it has high safety, and can be an excellent agent for preventing and/or treating glaucoma etc.

TECHNICAL FIELD

The present invention relates to a compound represented by the generalformula (I)

(wherein all symbols represent the same meanings as those describedbelow), a salt thereof, or a solvate thereof, or a prodrug thereof(hereinafter, abbreviated as present invention compound in some cases).

BACKGROUND OF ART

Glaucoma is an ocular disease having the characteristic of a visualfunctional disorder which causes a transient or permanent visual fielddefect and decreased vision. This is derived from that since an aqueoushumor is accumulated by a circulatory disorder of an aqueous humor, andan intraocular pressure is continuously increased, an optic nerve iscompressed. Decrease in an intraocular pressure is effective fortreatment of glaucoma and, in order to decrease an intraocular pressure,for example, drug treatment (eye drops, internal remedy, infusiontreatment), laser treatment, or operation treatment is performed.

Previously, among prostaglandins (PGs) which are physiologically activesubstances, as those that decrease an intraocular pressure, PGFs andPGIs are known. Development of a drug for treating glaucoma or ocularhypertension is being progressed using derivatives of them, and thereare some drugs which are actually sold (e.g. latanoprost etc.). However,the existing glaucoma treating drug alone is insufficient in intraocularpressure lowering action and sustainability of drug efficacy and, in atsite of glaucoma treatment, since administration at a frequent time or ahigh concentration, or therapy of joint use of drugs having differentmechanisms of action are being performed seeking stronger intraocularpressure lowering action, manifestation of side effects is feared. Forthis reason, drugs having stronger and sustaining intraocular pressurelowering action, and high safety are desired.

Meanwhile, as the prior art of the present invention compound, thefollowing PG derivatives are exemplified.

As a PG derivative having a bicyclic skeleton, for example, a compoundof the general formula (a):

etc., L^(a) is —(CH₂)_(da)—C(R^(2a))₂— (wherein da is 0 to 5, andR^(2a)s are hydrogen, methyl or fluoro, and are the same or different)etc., Q^(a) is an oxygen atom etc., R^(1a) is COOR^(3a) (wherein R^(3a)is hydrogen, alkyl of 1 to 12 carbon atoms etc.) etc., R^(4a) is:

(wherein R^(5a) and R^(6a) are hydrogen, alkyl of 1 to 4 carbon atoms orfluoro, and are the same or different, Z^(a) is an oxygen atom etc.,T^(a) is alkyl of 1 to 4 carbon atoms, fluoro, chloro etc., and sa is 0to 3) etc., V^(a) is a valence bond or —CH₂, W^(a) is —(CH₂)_(h), h is 1or 2, X^(a) is trans-CH═CH— etc. (a part of definitions of groups wasextracted) is known (see Patent Literature 1).

In addition, a compound represented by the general formula (b):

(wherein L^(b) represents —(CH₂)_(db)— (wherein db represents 1 to 5)etc., Q^(2b) represents O etc., R^(1b) represents —COOR^(19b) (whereinR^(19b) represents a C1-C12 alkyl group or a hydrogen atom etc.) etc., aring R^(22b) represents:

(wherein R^(4b) represents a hydrogen atom etc.) etc., R^(25b)represents:

(wherein R^(5b) and R^(6b) represent a hydrogen atom etc., Z^(b)represents —O— etc., T^(b) represents a C1-4 alkyl group, fluorine,chlorine, trifluoromethyl or —OR^(7b)— (wherein R^(7b) represents C1-4alkyl), sb represents 0, 1, 2 or 3, and X^(b) represents:

(a part of definitions of groups was extracted)) (see Patent Literature2) is known.

Further, a process for producing a compound represented by the generalformula (c):

(wherein A^(c) represents a C1-2 alkylene group, B^(c) represents a C2-6alkylene group, X^(c) represents C(O) etc., and Z^(c) represents a C1-4alkylene group etc. (a part of definitions of groups was extracted)) isknown (see Patent Literature 3).

Meanwhile, it has been reported that agonistic activity on an IPreceptor among PG receptors causes hyperemia and rise in a aqueous humorprotein, and inducement of stimulation on eyes has been feared (seeNon-Patent Literatures 1 and 2). For this reason, since the compounddescribed in Patent Literature 2 which is a PGI2 derivative hasagonistic activity on an IP receptor, there is a probability thatproperty of stimulating eyes etc. are induced.

Further, it has been also known that agonistic activity on an EP 1receptor among PGE subtype receptors causes itching of eyes (seeNon-Patent Literature 3).

The present invention compound is a compound which has low agonisticactivity on an IP receptor and an EP 1 receptor, and has selectiveagonistic activity on a FP receptor, but there is neither thedescription nor the suggestion regarding such the characteristic(selectivity) in any prior arts.

TABLE 7 Agonist activity on various prostanoid receptors: EC₅₀ value(nmol/L) FP EP1 IP Example 17 (23) 8.3 100 >10000 Example 17 (3) 3.03200 >10000 Example 17 (4) 8.8 >10000 >10000 Example 17 (25) 2.4857 >10000 Example 29 (12) 7.1 >10000 >10000 Example 321.6 >10000 >10000 Comparative Compound A 1.1 3 710

From the above results, it was seen that the Comparative Compound A hasagonist activity not only on a FP receptor, but also on an EP1 receptorand an IP receptor, while all of the present invention compounds havelow agonist activity on an EP1 receptor and an IP receptor, and haveselective agonist activity on a FP receptor.

(2) In Vivo Test

As can be easily understood by a person skilled in the art, in an invivo test, since regarding all test compounds, carboxylic acid which isan active body has bad corneal permeability, pharmacological action wasassessed by ocular instillation administration of a compound which hadbeen converted into an ester such as an ethyl ester, an isopropyl esteretc. In addition, in a group of the present invention compounds, byocular instillation-administering the ester body in an experimentalanimal (rabbit, dog etc.) by which pharmacological action is confirmedbelow and, thereafter, measuring a drug concentration of carboxylic acidin an aqueous humor, it was confirmed that the ester is rapidlyconverted into corresponding carboxylic acid.

(2-1) Intraocular Pressure Lowering Action

To one eye of a male dog (TOYO Beagle) which had been sufficientlyacclimated in advance was ocular-instilled 30 μL of each test compound(compound of Example 16 (35), compound of Example 16 (3) and compound ofExample 16(25)) which had been adjusted with a base (containing citratebuffer pH 6.5, 0.5% polysorbate 80, 1% propylene glycol, 0.01%benzalkonium chloride) to 0.01% (w/v) or 0.001% (w/v), respectively. Theother eye was not treated. As a positive control compound, latanoprostwhich is the known compound was used.

Thereafter, an ocular surface anesthetic (Benoxil eye drops 0.4%, SantenPharmaceutical Co., Ltd.) was subjected to ocular instillation tolocally anesthetize eyes, and an intraocular pressure of each testcompound before ocular instillation and after 2, 4, 6, 8, and 24 hoursfrom ocular instillation was measured. An intraocular pressure wasmeasured using a pneumatic applanation flat tonometer (Model 30 Classic,REICHERT). An intraocular pressure lowering rate (%) was calculated bythe following equation.

[Mathematic 1]

Intraocular pressure lowering rate (%)=(intraocular pressure valuebefore ocular instillation−intraocular pressure value at eachpoint)/(intraocular pressure value before ocular instillation)×100

Among measured values at each point, the result showing the maximumaction is shown in Table 8. An intraocular pressure of dogs to whicheach of the compound of Example 16 (35), the compound of Example 16 (3)and the compound of Example 16 (25) was ocular instillation-administeredexhibited the stronger intraocular pressure lowering action as comparedwith latanoprost which is a positive control compound.

To one eye of a male rabbit (NewZealandWhite, 2.0 to 3.0 kg) wasocular-instilled 30 μL of the compound of Example 16 (35), the compoundof Example 16 (3) and the compound of Example 16 (25) which had beenadjusted to 0.1% (w/v) with a base (containing citrate buffer pH 6.5,0.5% polysorbate 80, 1% propylene glycol, 0.01% benzalkonium chloride),respectively. Thereafter, an aqueous humor in anterior chamber after 0,1, 2, 4, 6 and 8 hours from ocular instillation was collected, and aprotein concentration in the humor was measured. As a comparativecompound, the aforementioned methyl ester of the compound of Example 12described in Patent Literature 2 (i.e. compound of Example 10 describedin Patent Literature 2) (hereinafter, abbreviated as ComparativeCompound B in some cases) was used.

Observation of the ocular general state was performed after 0, 1, 2, 4,6 and 8 hours from ocular instillation, and visual remark of cornea,iris, and conjunctiva was observed according to determination criteriaof the Draize method. A total of points of the resulting assessmentpoints of each item (=A₁×B₁×5+A₂×5+(A₃+B₃+C₃)×2) was assessed as aDraize score. Classification criteria of the Draize score was producedby referring to “Regarding Reference Material concerning Basic Idea ofBiological Safety Test, Administrative Notice Medical Device ExaminationNo. 36 dated Mar. 19, 2003, Pharmaceutical and Medical Devices Agency”.Classification criteria was as follows: A Draize score of 0 or more and5 or less was a non-stimulating substance, 5 or more and 15 or less wasa slightly stimulating substance, 15 or more and 30 or less was astimulating substance, 30 or more and 60 or less was an intermediatestimulating substance, 60 or more and 80 or less was an intermediate tostrongly stimulating substance, and 80 or more and 110 or less was astrongly stimulating substance.

Regarding any test compound, a dose until a dissolution limit (150 to1000 μg/mL) was administered and action of each active body wasassessed.

Results are shown in the following FIG. 1 and FIG. 2. The ComparativeCompound B was classified as a slightly stimulating substance from amaximum of the Draize score, based on its agonist activity on an IPreceptor and, further, since it also raises a protein concentration inan aqueous humor, it was seen that it induces the side effect on eyes.To the contrary, it was seen that all of the compounds of Example 16(35), Example 16 (3) and Example 16 (25) which are the present inventioncompounds were a non-stimulating substance by the Draize score, and hadno action of raising a protein concentration in an aqueous humor.

From the foregoing, since the present invention compound has low agonistactivity on an EP 1 receptor and an IP receptor, and has selectiveagonist activity on a FP receptor, it was suggested that not only it hasstrong intraocular pressure lowering action, but also side effects oneyes such as ocular itching action based on EP 1 receptor agonistactivity, and ocular stimulating property such as hyperemia etc. andaqueous humor protein rise etc. based on IP receptor agonist activitycan be avoided.

(2-3) Intraocular Pressure Lowering Action in Monkey Under Consciousness

To a left eye of a male monkey (crab-eating monkey) under consciousnesswas ocular instillation-administered 30 μL of a solution obtained byadjusting a test substance using the same base as that described aboveand, to a right eye was ocular instillation-administered 30 μL of asolution of only a base as a control, respectively. An intraocularpressure after administration was measured with time from administrationinitiation to after 24 hours. Upon measurement of an intraocularpressure, a crab-eating monkey was fixed on a monkey chair, and themonkey was anesthetized by ocular instillation-administering an ocularsurface anesthetic (Benoxil eye drops 0.4% Santen Pharmaceutical Co.,Ltd.). After mounting of a blepharostat (Handaya Co., Ltd.), anintraocular pressure of both eyes was measured (5 to 8 examples pergroup) using a pneumatic applanation flat tonometer (Model 30 Classic,REICHERT). A difference in an intraocular pressure value between controleyes and eyes to which a test substance had been administered, wascalculated as an intraocular pressure lowering rate using the followingequation, and sustainability of intraocular eye lowering action wasassessed using a maximum intraocular pressure lowering rate duringmeasurement and an intraocular pressure lowering rate after 24 hours. Asthe test substance, the Comparative Compound B, and the compounds ofExample 16 (3), Example 16 (25) and Example 16 (35) were used, and anadministration dose was 10 μg/mL in all cases.

[Mathematic 2]

Intraocular pressure lowering rate (%)=(intraocular pressure value ofcontrol eyes−intraocular pressure value of test substance−administeredeyes)/(intraocular pressure value of control eyes)×100

The results are shown in the following Table 9. It was seen that, in theComparative Compound B, a maximum intraocular pressure lowering rate wasinsufficient and, additionally, the lowering rate was reduced to lessthan 10% after 24 hours, and intraocular pressure lowering action cannotbe sufficiently maintained. To the contrary, it was seen that all of thepresent invention compounds are compounds which have a high maximumintraocular pressure lowering rate, and can maintain an intraocularpressure lowering rate of about 15% or more even after 24 hours, andhave strong and sustaining intraocular pressure lowering action.
